VERY concise UI, but has everything you need.
(Mac) it Pushes everything over to the Finder as an attached device (IE each Cloud Storage = an attached Drive. Perfect - just what I want. Allows normal Finder navigation browsing drag n Drop and Load/Save of files for the cloud vendors instead of having to navigate (multiple) cloud interfaces. True one stop shopping for both my work and personal files, yet each is nicely segregated (mandatory for my worktype)
Full Disclosure: I Received a gratis license for a review. But that was because I wanted to tout the benefits of this great product and because my use case is to have MULTIPLE cloud accounts for different reasons and purposes, yet needing to keep them segregated but handy. This UI is simple - for Mac it's an icon in the toolbar, and just like email account setup it Includes options to link your accounts for A3/AWS/Glacier, BackBlaze, Amazon Drive, One Drive personal/Business, Sharepoint (best access to Sharepoint files I've had so far), Google Drive/Cloud, Dropbox/Box, Owncloud, Rackspace, Open-stack, Dream Objects, Hubic -- plus SFTP/FTP, WebDav CIFS/SMB. IE All the biggies and all the self-service types as well. AWESOME!!! So then you can either quick reference the link via clicking on the icon you have 3 options - disconnect (eject), Browse (pop open the Mac finder window with your files) or click a right arrow (opens via GUI dropdown, great for quick access). You simply hover over these and it indicates what the function is - and if you hover over the file in the GUI dropdown, there's icons to open file (finder) or get (copy to clipboard) the shareable link. Wow ! Rare that I'm this excited about an App - one of those which just kind of saves the day on a regular basis productivity wise.
They don't seem to have iCloud as an option for it, but that is fine for Mac as iCloud Drive already functions this way - but could be handy to get a quick shareable link for iCloud Drive as well. Absolutely no (significant) complaints. I suppose they could add more cloud vendors (NextCloud is supplanting Owncloud in the marketplace for instance) but my needs are fully covered with what they have.
This isn't something you need to worry about if it's useful or if it's annoyance ware. If you would like one quick place to get to your cloud files and like the idea of managing them in the OS's File Manager as if they were an attached drive, then you're in business - and connecting the cloud accounts couldn't be easier. Get the trial and you'll be ready to pay for the app in just a few minutes - knowing you'll never want to get rid of this little jewel. Sounds like I'm a Schill but seriously I'm just excited about the app. Rare that they make the Swiss Army knife just the way you want it.
Benefits: This is the only realistic (sane) option I've seen to be able to segregate (and drag N drop) files around from multiple cloud vendors without having to navigate each as a separate app (most of which are PITA) or of course multiple browsers (horrible). This primary benefit is the whole point - treat all your cloud accounts as if they are separate devices. Isn't this what everyone wants? I can't imaging needing or wanting to use it any other way as the default way to interact if you are accessing this from your workstation (PC).
